RAILWAY-SPLICE VJI'll-I FISH-PLATES.

Specification of Letters Patent.

Serial No. 686,855.

1 0 all whom it may concern I Be it known that we, O'rio Armor KU- nrnr, subject of the King of Hungary, and Ti-inooon Fnniimnn Konn VON VVEIDENHEIM,

subject of the Emperor of Austria, residingat Steingasse 36, Vienna, III, in the Province of Lower Austria and Empire of Austriallungary, have invented certain new and useful Improvements in Railway- Splices with Fish-Plates, of which the following is a specification.

Our present invention relates to improvements in railway splices with bridging fishplzjes, which are secured to the rail ends MIC has for its object to take up the wheels atrthe" rail joint and to guide them from one rail to the other. By means of the said bridging fish-plates the shocks against the wheels running over the rail joint are diminished. But with the arrangements hitherto used such shocks in case the wheels drive from the rail upon the fish plate and run down from the same upon the rails, could not be avoided, for the reason that with the fish-plates commonly used a sudden lifting or lowering of the wheels takes place, the running or head. face of such wheels becoming worn away during working at a part or its breadth, so that owing to the stepped or shouldered tread of the wheel the latter cannot drive up and down without shock. This drawback is obviated bythe present invention. According to this invention the head or upper surface of the-bridg' ing fish-plate is beveled oil" at the outer side by a sloping transverse face, which inclines toward both ends of the fish-plate, so that the beveled or sloping part or the top surface or head of the fish-plate increases in breadth toward both ends, while the inner side of the fish-plate head, i. e., the side adjacent to the rails, is even or inclines slightly toward both ends of the fish-plate, at a part increasing in breadth toward the middle. T he said construction has for its object that the wheels, however great the wear may be, find points-of the sloping face from which they may drive up and run down the fish-plate gradually so as to avo d any shock which may be exerted upon the wheel otherwise. 1

The arrangement may of course be such that the fish-plate will be wedged automatically within. the groove of the bottom plate or between the said bottom plate and the rail,

in case the fish plate will be moved lengthwise ow ng to the migration tendency of the rails, so that migration of the rails is avoided perfectly; Moreover the invention enables especially the lower parts of the joint to be attached closely and tightly together, and

this circumstance may be made use of preferably in electric railway plants for direct cur-rent transmission. In the said plants the fislrsplates hitherto used are not sufiicient at present for direct chi-rent transmission in case the rail is used as current conductor. 'lherefore copper 'rail bonds are used for conductively connebting the rails, but such connecting bonds are expensive and 've rise to other inconveniences, as e. 9., lie ilities to injury from atmospheric influence ordandalism. The lower adj accnt faces of the fish plate and rail being tightly jointed together according to the present invention, separate connecting pieces such as copper bondsare dispensed with, for by the tight and close connection of the separate parts a suiliciently reliable current transmitting face is formed. In order to increase the security in the electric connection and to prevent loss of the transmitting capacity by formation of rust the fish-plates may be pro vided at the inner side with a galvanic conducting coating.

l/Vith the railway splices hitherto used such coating would be useless, for the reason that the several parts contact with each other only in few points and would there be scoured off constantly by the shocks, so that the coating would disappear. In the construction according to the present invention such danger is obviated owing to the extended contacting faces and the tight, intimate contact of the same. Instead of a coating a conducting mass such as mercury amalgam may be used.

The railway splice according to the present invention responds therefore to all requiremenls'in respect to avoiding shocks, security of the connection and reliable current transmitting.

The accompanying drawings show an ex ample of execution of the present invention.

Figure 1 shows the improved rail. oint in cross section, Fig. 2 in elevation and Fig. 3 in plan view, and Fi l shows a plan view of the fish-plate, a series of consecutive cross sections being represented below. Fig. 5

and Fig. 6 is a horizontal section taken on the line A-A in Fig. 1. I

The rail (1 with the lower flange m is held on both sides by two fish-plates b and c which fit partly to the rail head, the lower parts of b and being closely adapted or connected to the web and lower flange of the frail a.- The head or running face oi" the lfish plate c (Fig. 4) is at the inner side i. 6., at Z,*-even or inclines slightly endsof the fish-plate, while it is beveled at the outer sille' bya sloping transverse face dvltich inclines toward both ends of the fishtoward both late. 'llhesloping part of the upper or mrni'ining face of the fish-plate increases therefore in brcadthtoward both ends. As shown in Fig. kthe slopingrface may also be composed of continuous surfaces with successive cross-sections k, i, k of different inclinations. The parts is, i, k may have also equal inclination or equal sloping angles in worn wheel rim that the wheel will always be lifted. and lowered gradually however great the wear of the wheel tread in breadth andheight may be.

'With the usual fish-plates, the 'upper or running surface OfjWhlCh has noinclinati on in transverse direction, but is beveled at the ends in longitudinal direction, the wheel will be lifted on runningover the rail joint under all circumstances.

case also for every position of the wheel on the track, no matter how the wheel travels.

or fish-plate by such degree as corresponds to the depth of the recess resulting from the wear of the wheel tread. Therefore shocks are exerted to thewheels running up and down the fish-plate. Such shocks are perfectly avoided by the shape according to the present invention, for the reason that sudden lifting and lowering of the wheels cannot, take lace. curvatures, w ere the carriages will be thrown outwardly, it may happen that the unworn edge part of the tread of the Inner wheels wholly travels upon the, elevated part of the fish-plate. Biit, as the wheel runs up in a gradually mounting wa' in as much as the unworn or elevated e ge part finds always a suitable point of the sloping face at the end of the fish-plate, from which point the said edge part may begin to run up, violent shocks or thrusts are avoided The same is the At points of track by a greater measure upon the buter or inner side of its rail. The said particular and perfect effect results only from the special construction of the bridging fish-plate as can be understood. by the sections illustrated in Fig. l and by the perspective view (Fig. 5).

The two fish-plates b and c are rigidly connected to the rail a by the bolts 9. The

lower flanges or bases of the two rails are 7 supported by-a base plate d, which is provided at both sides with upper longitudinal projections c. The projections are provided at their inner sides with longitudinal grooves p, which are closed at both ends by 8 oblique or curved faces 79. Corrcspondingly the ends of the lower flanges f of the fishplates engaging the grooves are tapered or curved conically as at f, so that, in case the rail has a tendency to creep, the tapered or g conical end of the fislrplate will be wedged at p and prevent such migration. If violent transverse thrusts take place the lower flange f of the fish-plate will be forced into the respective groove 72, owin of the lower part of the fis rplate which part acts as a bell crank lever, so that the rail will be given greater rigidity in lateral or transverse direction.

The spaces between the flanges fund the a lower flange or base in of the rail 2'. e. the grooves p of the base plate 03 may be filled up with a. current conducting .mass such as mercury amalgam, or thin sheets 0 of copper or the like may be interposed for the pur- 1 out of the groove of the base plate, such 1 groove being open at both ends.
